You wouldn’t have known by the sound of Richard Schaefer’s voice the main event of tonight’s boxing show at the Barclays Center was in jeopardy.

Former four-division titleholder Erik Morales failed a random drug test administered by the U.S. Anti-Doping Agency and his status for tonight’s card remained uncertain as of late last night.

Morales, a boxing legend from Mexico, is scheduled to face Danny Garcia of Philadelphia for the WBC/WBA junior welterweight titles. It’s one of four title fights to be televised by Showtime.

Morales reportedly tested positive for clenbuterol, a drug used to treat breathing disorders but also can encourage weight loss. A second sample will be tested for confirmation, but a result is not expected until after the weekend, allowing the fight to continue.

“I’m happy USADA is going through the process,” said Schaefer, the CEO of Golden Boy Promotions. “It’s a full transparent process and they will rule later on their findings.”

If Morales were pulled from the card, boxing’s return to Brooklyn will still go on. A special night is planned with many of Brooklyn’s past champions, including Mike Tyson, expected to be in attendance.

“How many times have you seen four world titles fight in one night and it’s not on pay-per-view?” Schaefer said. “Having Danny Garcia make his return is the icing on the cake. It’s a very diverse card, just like Brooklyn and New York,” Schaefer said. “There’s a little bit for everyone.”

This is the first boxing card in a three-year deal Golden Boy Promotions signed with the Barclays to serve as the exclusive promoter for boxing. The initial plan was to have one boxing show a month at the facility. But Schaefer doesn’t want to sacrifice quality for quantity. Officials from Barclays and Golden Boy will meet this week to discuss more definitive plans and whether the next card will be either December of January.

“I want to make sure the market will carry that many shows,” Schaefer said. “I don’t want to over play the market either.”
